I was just wondering if there exists any (free) product or articles that demonstrate having editable pages. Essentially what I don't want is a full blown Content Management System, but rather the ability to assign certain pages as editable to authenticated users.

Does such a thing exist?

Not really, I wanted a more complex form of that. Besides contentEditable only works on IE5.5+ so that's a no go.

Imagine a single page Wiki, basically I want to design the pages around the site not the site around the wiki. If that makes any sense?

Looks like I'll have to roll my own.

It's closer but not exactly what I want. I think I'll just use something like FreeTextBox and retrieve the contents at runtime from an xml file or something.

ActiveX Control that Communicates with Client Side Devices

I'm trying to interface a barcode scanner and a website using activeX. I have code that will read the barcode, but my issue is developing an activeX control that will run on the client machine to pick up input from the barcode scanner device. I am having trouble finding much on activeX control creation, let alone interfacing my activeX control with a device on the client machine.

If it isn't possible for the control itself to interface with the client side device, then is it possible to wite a C# windows app that the active X control installs on the client machine and then communicates with?

Thanks

Try searching for COM Server[^] rather than activeX

If your code works then it works. If you make it part of a COM Server it will still work, the COM Server part just uses a specific way for the hosting application to interface with your code. That said there are possibly security issues when your COM Server is hosted in a browser that you might have to deal with. Again that is an entirely separate issue from the other two.

Transparent layer on web page

Hi

I would like to know how to show a transparent layer on a web page. The transparent layer should allow web controls to be placed and the data should be available to be submitted. Once the form in the transparent layer is submitted, the underlying web page should become active.

Can someone help?

Thanks in Advance.

You can use panels and set them visible or invisible as needed.

Or a MultiView

Converting a integer value of 0 to empty string when binding to a DataGrid

I am binding a generic list of products List<products> to an ASP DataGrid and was wondering what the best way to convert the Product object integer values of 0 to an empty string when binding to the grid. See, the Product object contains integer properties and when reading from the database if the value read is DBNull I assign a value of 0 to the property. Now, when displaying the List<products> using databinding I want the 0 to show as empty strings in their columns. What do you recommend?

Thanks,

Steve

I would recommend a string property you bind to, that returns an empty string if it's 0. Or use int? and then use ?? to return an empty string, perhaps ?

Printing to non default printer from ASP.NET Page [modified]

I am trying to print to a receipt printer during our payment process.

The printer is not the default printer and I can't change that.

The problem is that from the browser you don't have permission to programatically get
a list of printers and select which one you want. So, currently we pop up the Print dialog
then select the desired printer and then click ok. This is two steps too many.

How can you get around this limitation and automate the printing of the receipt?

No, you cannot. As you said, in javascript, you can kick off the printing process, but you can't interact with it.

So, I guess we could create a client side windows web service which accepts the html and then have the web page post to it and then it could do the printing.

Well, a client side app that calls a web service, yes, that would work. Or an ActiveX control perhaps.

Yes, I didn't what to do an ActiveX control but either way it is a client side solution.

The default JavaScript does not have the privileges of choosing a printer. You may need an ActiveX Solution to do that. Check out ScriptX, the basic version of which is free. I also have a small review of the same over here:
